Power supply and method for dual process welding

Abstract

A method and apparatus for providing welding-type power that alternates between at least a hotter and a colder process is disclosed.

The invention claimed is: 
     
       1. A method of providing welding type power for a single welding operation, comprising:
 (a) providing a first welding process having a first welding process power; 
 (b) then ending the providing of the first welding process providing a second welding process having a second welding process power, wherein the second welding process is a hotter welding process than the first welding process and the first welding process is a cooler welding process than the second welding process; 
 (c) then ending the providing of the second process welding power; and 
 (d) repeating (a)-(c) a plurality of times in a single welding operation wherein a welding system provides the first welding process and the second welding process; and 
 (e) receiving a signal from outside of the welding system and wherein ending the providing of the first welding process and ending the providing of the second welding process are done in response to the receiving of the signal from outside of the welding system. 
 
     
     
       2. A method of providing welding type power for a single welding operation, comprising:
 (a) providing a first welding process having a first welding process power; 
 (b) then, in response providing the first welding process for a first length of time, ending the providing of the first welding process and providing at least a third welding process having a third welding process power after ending the providing of the first welding process, and ending the providing of the at least a third welding process after providing the at least a third welding process and providing a second welding process having a second welding process power, wherein the second welding process is a hotter welding process than the first welding process and the first welding process is a cooler welding process than the second welding process; 
 (c) then, in response to providing the second welding process for a second length of time, ending the providing of the second process welding power; and 
 (d) repeating (a)-(c) a plurality of times in a single welding operation.
